T 0 all whom it may concern:

Be it known that i, VJILLIAM li irNEn, ncitizen 'th lh'iited Ste .3,1...:1. citgo, in the county of Cool; and Stste of Illinois, haveinvented a new and useful irnprovement in Antif' iction CentenBenri QZsfor Railway-Cars, of which the li'illowing is s specification.

My invention relelzes anti-friction. center bearings v The object of myinvent is to provide an anti-friction center he: iiifor railway ears orother rehioles of e. si nnio, strong, eflicient and durshl construction,in which the wearing tread members of the center plates may he removableand reversible so that when the Wearing faces or treads become worn,they may be reversed, thus doubling or in creasing the life anddurability of the center bearing, and so thst the Wearing trend memhorsmay h- I o ed ror wed when "*orn out Witl. o expense,

their inner ends against the spider hub, and that the spider hub in turnabuts snugly against the hub of the lower center plate. It results fromthis construction that there is, laterally, no looseness between theparts of the center bearing but that the rollers serve as direct bracesbetween the two center lates to receive the great side thrust of a ieavycar taking a curve at high speed. Also the arrangement. is such that therollers, while so taking the side thrust, may still actantifrictionally.

I claim i 1. In an anti-friction center bearin for railway cars, thecombination with a body bolster, of an upper center plate securedthereto, provided with an annular cone tacedsocket to receive aremovable annular tread, a truck bolster, a lower center plate securedthereto, having a cone faced socket to receive a separate pieceremovable annular tread, upper and lower se arate piece double conefaced reversible annu ar treads fitting in the sockets of the upper andlower center plates, the anti-friction conical rollers interposedbetween the center plates and their separate piece annular treads, and aroller spacing spider, substantially as s ecified:

2. In an anti-friction center caring for cars, the combination withupper and lower center plates furnished with annular conical sockets toreceive removable annular conical treads, of upper and lower separatepiece double cone faced reversible annular treads fitting in the socketsof the upper and lower center plates and anti-friction conical rollersinterposed between'said treads, substantially as specified.

3. In an anti-friction center bearing for cars, the combination withupper and lower center-plates furnished with annular conical sockets toreceive removable annular conical treads,' of upper and lower separatepiece double cone faced reversible annular treads fitting in the socketsof the upper and lower center plates and anti-friction conical rollersinterposed between said treads, and a piolller spacing spider,substantially as specier.

4. In an anti-friction center bearing for railway cars the combinationwith body and truck bolsters, of upper and lower center plates, securedthereto and furnished each with an annular cone faced socket, removableand reversible double cone faced treads fitting in said sockets, conicalrollers between said rplates and a radial arm s ider having a hub ttinga hub on one of saio center plates, substantially as's ecified.

5. In an antiiction' center bearing for railway cars, thecombinationwith body and truck ,bolst'ers, of upper and lower center plates securedthereto and furnished each with an annular conefaded socket, removableand reversible. double cone faced treads, fitting in said sockets,anti-i'riction conical rollers between said treads, and a roller spacingspider having a hub fitting a hub on one of said center plates andprovided with radial arms extending between adjacent rollers,substantially as specified.

6. In an antifriction center bearing, the combination of upper and lowercenter plates having annular conical treads and telescoping annular hubsand telescoping annular rims, the annular hub of the upper late fit tingwithin the annular hub of t e lower plate and the annular rim of thelower plate fitting within the annular rim of the upper plate, conicalrollers between said lates, and

a roller spacing spider having a hu and provided with radial armsextending between adjacent rollers, said rollers abutting at their outerends against said outer annular rims of the said upper and lower centerplates and abutting at their inner ends against the outer face of thehub of the spider, the inner face of the spider hub abutting snuglyagainst the hub of the lower center plate, so that the said rollers willserve to brace the center plates against side thrust of the car and alsoact antifrictionally when under such side thrust, substantially as setforth.

'7. In an antifriction center bearing, the combination of upper andlower center plates having ann'ular conical treads, telescoping annularhubs and telescoping annular rims,

the annular hubs of the upper late fitting within the annular hub oi thelower plate and the annular rim .of the lower plate fitting within theannular rim of the upper late, antifriction rollers between the saidplates, and a roller spacing spider having a hub fitting and snuglyabutting on the hub of the lower center plate and having radialoutwardly ta ering spacing arms 'extending between an bearingeripherally against adj a: cent rollers, said rol ers abutting at theirouter I ends against said outer annular rims of the 'said upper andlower center plates and abutting at their inner ends against the outerface of the hub of the spider, so that the said rollers will serve tobrace the center plates against side thrust of the car and also actantii'rictionally when under such side thrust, substantially as setforth.

8. In an antifric tion center bearing, the combination with upper andlower center plates having telescoplng annular hubs and telescopingannular runs, the annular hub ofthe upper plate fitting within theannular.

hub o the lower plate and the annular rim of the lower plate fittingwithin the annular rimof the 11 per plate, and antifriction rollers be-'tween the sa1d plates, of a roller spacing spider having radial armswith curved bearing faces to engage the rollers, and provided with ahub, the sa1d rollers abutting at their outer ends against said outeupper and lower center their inner ends agains hub of the spider, 5 hubabutting snugly a lower center plate,s0 th to brace the center platesagainst side thrust the inner face of the spider r annular rims of the lof the car and also act antifrictionally when I plates and abutting atunder such side thrust, substantially as set t the outer face of theforth.
